We're dividing 120595 by 12 
We're looking to find how many times 12 goes into 120595.

Moving on to step 1:
12 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 12

Moving on to step 2:
If we divide 12 by 12, we get 1 and a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 12 from 12, we get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 12

Going ahead to step 3:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 0 leaves us with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 12

Step 4:
The number 12 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 12

On to step 5:
59 divided by 12 is 4 with a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 1004.0
Subtract 48 from 59 to get 11.
Take the next digit (5) from the dividend and append it to 11, then repeat: 115 / 12

On to step 6:
When dividing 115 by 12, we get 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 10049.0
If we take 108 away from 115, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
The number 12 fits into 70 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 10049.5
If we take 60 away from 70, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
12 goes into 100 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 10049.58
Deduct 96 from 100 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 9:
If we divide 40 by 12, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 10049.583
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
40 divided by 12 is 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 10049.5833
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 10049.5833, and the remainder is 4e-05.
